Social media & influencer hype
Many reviewers explicitly say they bought it after seeing it go viral on TikTok or hearing influencers rave about it, driving strong trial purchases.
Brand/ingredient reputation (PDRN)
Consumers cite trust in medicube's PDRN line and the promise of PDRN plus collagen as reasons for purchase, often pairing it with the brand's PDRN ampoule/serum.
Repurchase/loyalty
A notable share of reviews state they are repurchasing after previous satisfying use, indicating a loyal repeat-buyer base.
Aesthetic appeal / gifting
The pink color and packaging is repeatedly called out as a purchase driver ('I love how these are pink'), suggesting appeal as a gift or Instagrammable item.
Sale/discount pricing
Several Korean-language reviews mention buying during sale periods due to the otherwise high per-sheet price.
